Right... so now everything else is to blame except for the actual cause? SegWit and Lighting have no relevance to this matter whatsoever. The economic incentive was there, so some people took advantage. That's all there is to it. It also bit them in the ass in 2015 when they got it wrong and cost themselves money by building on the wrong chain. So perhaps they learned something and will be less likely to make the same mistake again. The network is resilient enough for it not to be a major issue. Whatever we were debating in the community at the time, it wouldn't have changed a thing. The miners tried taking a shortcut and paid the price for their lapse in judgement. They should now understand the importance of validating.
A new promising technology naturally faces challenges and obstacles? Whose responsibility is to keep it safe and secure other than its community and the devs?
The thing that keeps it in check is the alignment of incentives. You know, that thing you arrogantly think you can screw around with and there won't be any consequences? That.
Blame whoever you want, I still think you're an arrogant tool. Devs aren't here to bow to your every whim. They have the freedom to work on whatever appeals to them. Again, you clearly care about pools and ASICs more than anyone else does. If it's so important to you, go start your own coin where those elements don't factor into it.
I consider your technical arguments wrong and confused.
